Speaker apparatus

Abstract

A speaker apparatus includes a pair of speakers and a connecting member. The pair of speakers is arranged in an interior of a structure protruding into an interior space of a vehicle. The pair of speakers has respective diaphragms facing the interior space of the vehicle and that are directed in opposite directions from each other. The pair of speakers has back surfaces that face each other. The connecting member inter-connects respective drivers of the pair of speakers and is connected to back surface sides of the drivers.

What is claimed is: 
     
         1 . A speaker apparatus comprising:
 a pair of speakers that is arranged in an interior of a structure protruding into an interior space of a vehicle, the pair of speakers having respective diaphragms facing the interior space of the vehicle and that are directed in opposite directions from each other, the pair of speakers having back surfaces that face each other; and   a connecting member that inter-connects respective drivers of the pair of speakers and is connected to back surface sides of the drivers.   
     
     
         2 . The speaker apparatus according to  claim 1 , further comprising:
 an enclosure that is arranged in an interior of a center console of the vehicle, the enclosure having openings that face respective left and right side walls of the center console;   wherein the pair of speakers is arranged in respective left and right openings of the enclosure.   
     
     
         3 . The speaker apparatus according to  claim 2 , wherein
 another member other than the pair of speakers and the connecting member is arranged in an interior of the enclosure.   
     
     
         4 . The speaker apparatus according to  claim 3 , wherein
 the enclosure contains an electromagnetic wave shielding material.   
     
     
         5 . The speaker apparatus according to  claim 3 , wherein
 a sound wave absorber/scatterer for absorbing/scattering sound waves is provided on an outer periphery of the another member in the interior of the enclosure.   
     
     
         6 . The speaker apparatus according to  claim 2 , wherein
 at least a part of the enclosure is configured by at least one of a housing of the center console and a frame of a floor of the vehicle.   
     
     
         7 . The speaker apparatus according to  claim 2 , wherein
 the enclosure is configured in a box shape having an opening in a bottom and is arranged on a floor of the vehicle so that the floor closes the opening in the bottom of the enclosure, and a sealing part is interposed between the opening in the bottom of the enclosure and the floor.   
     
     
         8 . The speaker apparatus according to  claim 1 , wherein
 the pair of speakers includes inputs by which sound source signals of a right channel signal and a left channel signal are input to the pair of speakers, respectively.   
     
     
         9 . The speaker apparatus according to  claim 1 , wherein
 the pair of speakers includes inputs by which in-phase monaural source signals are input in a low-pitched sound range and stereo source signals are input in a high-pitched sound range.
